FRANCIS JOSEPH MILLER, OF NEW YORK, N. Y.

STOP-cocK.

Specification of Letters Patent No. 3,7344, dated November 21, 1843.

To all whom t may concern:

Be it known that I, FRANCIS JOSEPH MILLER, of the city of New York, inthe State of New York, have invented a new and Improved Jet-Pipe forDelivering lVater, Steam, &c.; and I do hereby declare that thefollowing is afull, clear, and eXact description of the same, referencebeing had to the annexed drawings, making a part of this specification,of"which Figure l is a cut section of the lpipe through the center, andFigs. 2, 3, 4, 5 and 6 views and Sections of the several parts of it,like parts being indicated in all by the same letters of reference.

The nature of my invention consists in making the pipe constitute ofitself a Stop cock, by which in cases where a cock is necessary, thepipe is rendered more easy of construction and offers less obstructionto the passage of the fluid.

At the end where the pipe is attached to the hose, or vessel, is a bulb,containing within it a cavity of a conical shape having a ground face;the end of the pipe inserted in the bulb has also a ground face, andbecomes in fact the plug of the cock.` It has holes in the sides, which,when they are opposite corresponding holes in the sides of the cavity inthe bulb, let the fluid into the interior of the pipe. `When the pipe isturned so that the holes in it and the bulb no longer coincide the fluidis shut olf. The turning of the pipe within thebulb is regulated in thefollowing manner: A notch d is cut in the upper side of the bulb extend`ing from the conical hole outward and about one third of the way aroundthe bulb; a pin inserted in the Side of the pipe and projecting from itabout 1b of an inch extends into this notch and moves freely in it untilthe pipe is so far turned as to bring the pin against the faces orshoulders `.which form the sides of the notch. The limit. of the pinsmotion in one direction lets the fluid on in full force, in the othershuts it wholly off the parts are kept together by a Screw inserted inthe lower end of the pipe. Y

A, thepipe; a, pin in the side of the pipe to regulate its motion withinthe bulb; B, the part of the pipe which forms the plugg, Z), holes toadmit the water to the interior of the pipe; C, the bulb which has ascrew thread at the lower end` to attach it to the hose or vessel c,openings in the side of the cavity within the bulb; s, screw to keep thewhole together.

WhatI claim is The mode herein described of combining a jet-pipe andstop cock, that is to say maklng the jet-pipe the revolving part of thestop cock in the manner herein set forth, orV

any other substantially the same..
